Spywares, virus, keylogger are installed in different directories, hidden directories, or it is hidden among thousands
of files. SO mahirap i-identify.
1. Need to use any free or any AV's or not
2. Click start msconfig startup
Now you can see all your startup programs
3. Disable all startup running programs. OFF your firewall and AV
4. Restart PC. open msconfig again If you see na may enabled start up programs.
That program for sure is a virus/spyware/keylogger. Take note of the name and its location
5. If you see program that is not enabled, meaning you are free of any virus/keylogger/spyware.
6. Now if you want to delete, take note of its locations and name then manually delete it
or let your AV do the deletion by righ clicking its location
OR
maybe this is bit easier, Ive seen Ddrwang wall photo. Using his tuneup utilities, better to
always check your startup programs via tune up utilities.
open tune up click optimize system click disable startup programs then if you see malicious
program you will try to disable it then restart pc. If you that program enabled. probably
it could be a virus. To identify its location You can rightclick it and take note its location
to delete that Go to its location/directories then manually delete the files or its any subfiles
or via registry....
But the most effective way is the above method one.
